imac (27" mid 2011)

Hi After upgrading to replace the video card and processor, the iMac 27" 2011 does not turn on, the first LED on the motherboard blinks. After I took out the memory and battery overnight, the first LED began to light constantly, but the iMac still wouldn’t turn on. What could be the problem ?

The computer boots, I hear the startup tone, but the display stays black. On occasion the display turns on for a brief amount of time, I was able to run First Aid in disk utility (nothing), and even erased the HDD and reinstalled MacOS. But before long the display went black again and hasn't...

Hi, I have found this OEM blade SSD from an Late 2012 Imac 27" (768GB) on an auction-site here in sweden. I was wondering if I could fit it in my mid 2011 Imac 27". I don't mean if I physically can fit it in the Imac! I mean if I can use Cables from standard HDD?

Hello All This is my first post on MacRumours. Whilst I'm a long time Apple customer (have been using iPhone since 3G and have had a couple of iPads along the way...), I got my first iMac a few weeks ago. I was keen to learn iOS development (as a hobby) and a friend happened to be selling his...

My 2011 27" iMac died recently. While I've already moved on to a new PC (Intel i5-8400, GTX 1060), after 7 years of the iMac, I can't settle for a lesser screen, but I've found a lot of monitor options lacking in two big departments: Monitors often have narrow viewing angles Monitors often have...

UPDATE: On July 28, my iMac died. We had 7 great years together, but the GPU gave out and I've moved on to a PC, rendering this thread moot. I have a 27" 2011 iMac that I want to use as a monitor for a gaming PC I plan on building. I understand this will only work if I have a special device...
